By examining the econometric interrelationships of rice export prices of India, Thailand, Vietnam, Pakistan, the U.S., Argentina, Brazil, and Uruguay, this study examines the most influential rice-exporting countries in the international rice export market. The sampled countries are the source of more than 80% of the global rice exports. In the process, this study relies on online data portals of the United Nations and country-level sources for aromatic and non-aromatic rice export price information from India, Pakistan, and Thailand. This study employed the Prais-Winsten and Autoregressive Distributive Lag (ARDL) estimation processes with the error correction procedure. Combining the findings from both models, this study concludes that in terms of interactions, the non-aromatic long-grain rice price of the U.S., and the aromatic rice price of Pakistan are the most correlated prices in the international rice market. Considering the number of countries influenced by the price of a given country, our results indicate that Vietnam is the price leader in the non-aromatic long-grain market, followed by Argentina, Brazil, and India. India, the largest exporter, is the fourth top price leader. In the case of aromatic rice, Thailand is the absolute leader. Many countries in Asia and Africa rely on rice imports to meet domestic demand, where the food security situation is already precarious. Based on the findings, this study suggests closely monitoring rice production and export trends of Vietnam, Argentina, Brazil, India and Thailand to provide early warning when necessary to better manage supply shocks in the international rice market.

Official protection of an exploited species sometimes precedes any quantitative understanding of its use, including any dependence of local residents on it for food and livelihood. Conservation initiatives could suffer without this information. The Goliath frog Conraua goliath is iconic globally because of its large size, and is categorized as Endangered on the IUCN Red List. The main threat to this species in Cameroon is overexploitation, but any associated socio-economic aspects of this have not been quantified. We provide insights into local perceptions of the Goliath frog and its consumption through structured interviews with 223 people living alongside this species. The Goliath frog is well known and hunted both for home consumption and the wild meat trade. We trailed seven collaborative Cameroonian Goliath frog hunters over two seasons to determine offtake. A total of 192 Goliath frogs were collected by these hunters, peaking in March. The hunters used nets, shotguns and spears. Their catch was eaten at home or sold fresh within the community or to travellers for XAF 1,500–5,000 (USD 3–10) each. We also studied the Goliath frog trade by examining the databases of the Cameroonian Ministry of Forestry and Wildlife, and CITES. CITES and hunters reported large exports of Goliath frogs but no trade was documented by the Ministry of Forestry and Wildlife. To support conservation planning, this study provides preliminary quantitative information on the extent of the threat of hunting to this Endangered frog.

As in other countries, textile and apparel production in Germany is considered a victim of globalization. Domestic production and employment declined dramatically after its postwar peak in the late 1950s. Research has often attributed this trajectory to the trade liberalization policy of the German governments. However, this interpretation is puzzling. German trade policy was not as liberal as is claimed, nor did the industry disappear. This article addresses the issue using statistical evidence as well as archival material. The West German textile and apparel industry was using outward processing strategies comparatively early and was supported in that by German politicians starting in the early 1960s. As a result, the industry moved up the global value chain of textile production.

Morocco has a large number of edible weeds, but seventeen are mostly eaten by the population, collected for sale in different provinces, or even exported. Eight weeds have edible shoots while the others have edible stems, fruits, roots, flowers, or petioles. Thirteen weed species are marketed either seasonally or throughout the year and generate money for the people. Morocco's tassel grapehyacinth bulbs and products extracted from pennyroyal mint are exported. Further research should focus on the nutritive value of these weeds and their economic role in the country.

Policymakers are concerned about nitrogen and phosphorus export to water bodies. Exports may be reduced by paying farmers to adopt practices to reduce runoff or by paying performance incentives tied to estimated run-off reductions. We evaluate the cost-effectiveness of practice and performance incentives for reducing nitrogen exports. Performance incentives potentially improve farm-level and allocative efficiencies relative to practice incentives. However, the efficiency improvements can be undermined by baseline shifts when growers adopt crops that enhance the performance payments but cause more pollution. Policymakers must carefully specify rules for performance-incentive programs and payments to avoid such baseline shifting.

The relationship between exporters and independent foreign channel intermediaries (FCIs) is complex. The present paper analyses and discusses the potential types of opportunistic behaviour that might be engaged in by foreign agents or distributors (FCIs) using an agency theory approach. A classification framework of opportunistic behaviour is developed and a detailed qualitative examination of the content of five agency-distributor agreements between Australian exporters and their FCIs. A five-category classification scheme for opportunistic behaviour was found that included (1) product, (2) price, (3) information, (4) logistical, and (5) legal opportunism. The implications of each type of opportunism for an exporter are discussed using examples obtained from ways to control opportunistic behaviour are discussed.

In heterotrophic streams the retention and export of coarse particulate organic matter and associated elements are fundamental biogeochemical processes that influence water quality, food webs and the structural complexity of forested headwater streams. Nevertheless, few studies have documented the quantity and quality of exported organic matter over multiple years and under a range of conditions that includes both droughts and hurricanes. This study quantifies the export of coarse particulate organic matter (CPOM, > 12.7 mm), over 18 y in two headwater streams in north-east Puerto Rico. Daily exports ranged from 0 to over 170 g ha−1 d−1 and averaged 7.39 g ha−1 d−1, with similar amounts coming from leaves (3.5 g ha−1 d−1) and wood (3.2 g ha−1 d−1). Export of coarse particulate organic carbon was 3.0 g ha−1 d−1 which constitutes only 1.32% of carbon exports. Most litter falling into the streams was processed in place as only 2.3% of the leaf litter falling directly into these perennial channels was exported as CPOM. On average, 6 wk y−1 had no exports while events transporting more than 10 g ha−1 d−1 occurred every 2.8 mo. Instead of a single annual pulse as observed in deciduous systems, there were annual peaks in CPOM exports during May and September and less export during the drier period from December to February. Ratios of C:N in the exported material were highest in the driest month and lowest during rainy months, while leaf fluxes for nitrogen, phosphorus and calcium were highest in rainy months and lowest during February. Although median daily exports and exports during low- and base-flow periods were similar before and after Hugo, after 16 y exports during moderate- and high-flow periods were still less than those in the 2 y prior to the hurricane. Our observations indicate a system with high rates of internal processing that quickly returns to median daily conditions following hurricanes but requires several decades for storm-flow exports to return to pre-disturbance conditions and indicates that the long-term pattern of CPOM export is associated with the level of maturity of watershed vegetation.
